White Noise Generation

Program Features

• A program that generates 5 different types of noise.
• Composed of 3 functions for noise sample generation, applying a bandpass filter, and saving the generated samples.
• The generated noise is saved in WAV file format.

Key Features

• Configure the sampling rate and length of generated samples.
• Choose from 3 weighting filters.
• Specify the sound volume when saving samples (in dB).

How to Use

Each function can be used step by step. You can test all the processes by running the noise_generator.ipynb file.

1) main.py

a) generate_sample

• Generate noise samples.
  • sec: Duration of the noise to be generated.
  • sample_rate: Sampling rate.
  • color: Type of noise.
  • weight: Type of weighting filter.

b) bandpass_filter

• Apply bandpass filtering on frequency domain.
  • samples: Generated samples.
  • lowcut: Lower frequency for filtering.
  • highcut: Upper frequency for filtering.

c) save_sample

• Save the samples as WAV files.
  • samples: Generated samples.
  • db: Sound volume level.
  • file_name: Name of the file to be saved.
